Some schools are like this, and some are not. But different schools have different policies for sports students. For example, some schools do not take care of sports students' grades and give up if they fail. The exam is equally difficult, so they don't cover that chapter. Some school sports students can take care of them, take exams together, and their grades can be guaranteed. That will stamp the sports stamp. As far as I know, Zhejiang University is stamped with the seal of sports, and so is Tsinghua of Peking University. Nankai University doesn't cover it, but Nankai is really TMCD. The exam is as difficult as ordinary TM students, and I almost didn't graduate without taking care of extra points.
